[llvm-dev] DragonEgg for GCC v8.x and LLVM v6.x is just able to work

[Leslie Zhai via llvm-dev]

Dear Chris,

Thanks for your kind response!

The motivating of this work:

1. Clang can not build Linux https://bugs.llvm.org/show_bug.cgi?id=22830 
and LLVMLinux patch was not be maintained? 
http://llvm.linuxfoundation.org/index.php/Main_Page

2. Clang analyzer Frontend can not static analysis glibc or Linux 
https://bugs.llvm.org/show_bug.cgi?id=31017 but analyzer checker is able 
to find the bugs for KDE :)

3. For leaning GCC plugin, GIMPLE, LLVM IR, GCC PASS, LLVM PASS, 
CodeGen, etc. from llvm-gcc and dragonegg, thanks for your great job!

The usecase for dragonegg:

1. mips64-linux-gnu-gcc (WIP), arm-linux-gnu-gcc and x86 GCC Frontend -> 
GIMPLE -> LLVM IR -> Assembly or for KLEE

2. GCC Frontend -> GIMPLE -> Clang AST (WIP)

I am interested in some other frontend, such as flang-clang 
https://github.com/flang-compiler/clang/pull/28 and it is glad to learn 
from other developers :) https://gcc.gnu.org/ml/gcc/2017-09/msg00022.html

These will be split off from the LLVM project (e.g. to separate Github projects), allowing interested people to continue their development elsewhere. http://lists.llvm.org/pipermail/llvm-dev/2017-August/116266.html
